The sun flips its magnetic field intermittently roughly every 11 years because of a triggering dynamic intermediate axis formed by the outer convective zone.
Following the wedge sunspot model, it can heuristically be shown that the emergence of sun spots changes the mass distribution of the equator region relative to the polar region. Considering Poinsot's theorem, this results in a flipping motion of the semisolid convective zone and its magnetic field near surface, temporarily enhancing toroidal fields underneath. Due to an elevated steady energy state, the magnetic field in the inner convective zone sequentially flips as well.
Elaborate calculations based on accepted mass density estimations illustrate the triggering flip. Furthermore, two perpendicular dynamic smallest axes can occur which might explain the Dalton-Minimum. Consequently, a self-regulating solar energy feedback mechanism is conjectured.
